Ordered mesoporous carbon-supported calcium oxide materials have been rationally synthesized for the first time. Large specific surface area, high content of nanosized calcium oxides can be easily obtained and tuned. The structure, porosity and the particle size evolution as a function of calcium content and carbonization temperature are extensively characterized and well correlated with their CO2 sorption properties. The composite materials are of significance for CO2 physisorption at ambient temperatures with high capacity and selectivity over N2. Meanwhile, the nanocrystalline calcium oxides are highly active for CO2 chemisorption, with tuneable and high CO2 capacity at 200–500 °C. An almost complete initial conversion and fast reaction kinetics at a low temperature (450 °C) and low CO2 pressure can be achieved within minutes. Cyclic stability is also substantially improved due to the confinement effect of the CaO nanoparticles within the mesopores. These materials would be suitable for CO2 separation over a wide range of temperatures.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
